for the time being, I changed the diff to use IPv4 as the default. I build a (local and unoffcial) snapshot with it and deployed it on our production servers. There is no problem known to me atm. And update changed nothing, but allowed me to _optionally_ turn on IPv6 support.
If you want to help with testing, get the latest diffs from http://mini.vnode.ch/ (there was a problem with mod_rewrite and the proxy module fixed yesterday)
